[Bug, PRPL] GetSlotFromShip NullReferenceException

[MxGoldo]

I found a NullReferenceException that appears when GetSlotFromShip is called on a ship that has its slot after a slot with a ship that is not built. In the attached screenshot GetSlotFromShip works only for the ships in slot 0 and 1.
Because of this bug GetSlotFromShip is pretty useless.
